Since I don't have any comercial built solar panels, I would like someone to post the comment about this.
I use few 50 watts panels to charge my batteries. Now, we are talking of JUST ONE! Others are disconnected from the system for the testing purpose.
First, about the panel:
It consists 36 WB 29 cells from Plastecs. They are rated 1.8 to 2.0 Amps and 0.57 to 0.6 Volts.
If I calculate from that, I can get:
Voc would be 20.52 to 21.6 Volts
I (?) would be 1.8 to 2.0 Amps.
So, that panel is rated 37 to 43 Watts.
Is that right?
I can see commercial built panels have max power voltage of 17 Volts. Would the current be higher if I put the panel to 24 Volts battery?
